Is it safe to update dawn theme to version 8.0

Technical Q&A

Currently, I am running a Dawn theme version 7* and made many custom changes in the theme many JS CSS, and custom blocks.

So if I update my theme to version 8, will I lose all my custom changes?

There is any safe and better way to update my theme to the latest version?

Hello @zack100
Shopify dawn latest version have some other features of customized theme. as you said you have done JS , CSS code customization then when you update the theme it may have some changes or modification on your current theme if you will do manual update then it may take time to update manually for your theme you will have to customized from the scratch. In your case I recommend performing a manual update and then re-configuring apps you plan to keep, and re-adding any custom. Theme upgrade is time consuming work you need to have liquid and coding knowledge.

Any customization made to your theme using the Theme Editor are copied over and applied to the updated theme. These include:

  • Changing theme settings
  • Changing page layouts, like adding, reordering, removing, or hiding sections or blocks
  • Changing section or blocks’ settings, including adding images, videos, text, and data sources
  • Adding new templates
  • Adding, removing, or changing settings of app embeds or app extensions

Manual code changes to your theme files through the Code Editor (except files in the /templates folder and settings_data.json).

Hi @zack100 ,

Any custom theme update will not merge with the latest version. You have to implement all custom changes again in DAWN 8.0.

If you have documented the changes only then upgrade the theme.
